Cost to Dissolve Juvederm Same As Juvederm Injections?

Hyaluronidase per vials is a lot less expensive than fillers like juvederm and restylane. For this you are paying for the cost of the time from the injector and will depend on their rates on an hourly basis. For your lips, I wouldn't expect that would be more than $250 more or less. The doctor or injector that did your procedure should really help you with this to help you achieve the best results.
Don't worry, you can get your lips the way you want; it's not actually that hard as it seems. Before you get injections in your lips, it is helpful to go to a doctor with a great sense of aesthetics.

Great question!  Hyaluronidase is relatively inexpensive and should not cost nearly as much as your Juvederm injections.  However the person that does the injections needs to know what they're doing, so make sure you see a board certified plastic surgeon who is well versed in hyaluronidase injections.  

I typically charge $400 to dissolve Juvederm in a single session if the patient had their injection done elsewhere.  For my own patients, I don't charge if they ever choose to reverse the effect of Juvederm.
